Clinical application
（1） It is used to treat edema and difficult urination, and its diuretic effect is taken. The treatment of general water swelling is more suitable for those who are cold or have weakness of the spleen and stomach, and can be combined with Ze Xie and Zhu Ling to strengthen the diuretic effect. For those who also have yang deficiency, add Gui Zhi or Rou Gui to increase yang energy flow (that is, to increase blood circulation function. Whenever Gui Zhi or Rou Gui is added to diuretic herbs, it is to promote blood circulation and strengthen diuresis, which is the meaning of the so-called "gasification of water" and " increase qi and water flow"), such as Wu Ling San, suitable for mild edema. Experiments have proved that Wu Ling San has a strong diuretic effect, which can increase the amount of urine excreted by 112%.
（2） It is used for the treatment of Tan Yin. The experience of the predecessors is that "Fu Ling must be used for Tan Yin". It has the effect of diuresis and tonifying the spleen and stomach. Generally, Ling Gui Zhu Gan Tang can be used as the main recipe. Tan Yin in the stomach (upper abdomen full, stomach has a vibrating sound, vomiting water phlegm salivation, such as chronic gastritis), add Ban Xia, Sheng Jiang, or use Fu Ling Yin; Tan Yin in the lungs (cough, phlegm foam, poor breathing, such as chronic bronchitis, bronchiectasis), then add Chen Pi, Ban Xia, Chuan Bei.
（3） It is used to strengthen the spleen and dispel dampness, treat indigestion, upper abdominal distension, reduced appetite, and spleen deficiency and diarrhea caused by spleen and stomach weakness. Its first function is to nourish and tone the center; The second is diuretic to remove dampness, which reduces intestinal water and thickens loose stools. Those with stomach yang deficiency (about equivalent to insufficient digestive function) can use Fu Ling, but they need to be equipped with Dang Shen, which is what the previous experience said "Fu Ling can clear stomach yang" and "those with stomach yang deficiency must use Fu Ling". In short, if you have loss of appetite, indigestion, vomiting or diarrhea after eating, you can use Dang Shen or Ren Shen and Fu Ling, and other spleen and qi regulating medicines, such as Shen Ling Bai Zhu San. If it is diarrhea caused by acute dyspepsia, it is used with Cang Zhu and Jin Yin Hua.
（4） It is used to calm the nerves. Where there are palpitations and insomnia, you can use Fu Ling with sour Suan Zao Ren, Yuan Zhi, Bo Zi Ren, Wu Wei Zi, such as Bu Xin Dan (formula).

Annotations
1. Fu Ling Pi: Functional water dilution and reduction in swelling, mostly used for the treatment of skin edema. Its taste is the same as that of Fu Ling, but it specializes in diuresis and has no tonic properties. It is often used to treat mild edema (such as the face and limbs that can be seen after illness), and the representative formula is Wu Pi San (from "Zhong Zang Jing"). Prescription: Fu Ling Pi 15g, Da Fu Pi 9g, Sang Bai Pi 9g, Sheng Jiang Pi 6g, Chen Pi 6g, decoction in water. Note: If Fu Ling with skin is used, the prescription should be written "Poria with skin". It is mainly used for the treatment of general edema and slightly heavier ones, as the skin of Poria (called “Fu Ling Pi) has weaker tonic properties.
2. Fu Shen: The function is to calm the mind and calm the nerves, and it is mostly used to treat restlessness, palpitations and forgetfulness. Its taste is the same as that of Fu Ling, but it is good for calming the nerves. Animal experiments have confirmed that Fu Shen has a moderate degree of sedative effect, but it is not as good as Suan Zao Ren. Prescription: Fushen 9g, Fu Ling 9g, Huang Qi 15g, Dang Gui 9g, Chuan Xiong 4.5g, Fa Ban Xia 6g, Bo Zi Ren 6g,Suan Zao Ren 9g, Yuan Zhi 3g, Dang Shen 9g, Rou Gui Mo (added as powder in post) 3g, Zhi Gan Cao 6g, decoction in water.
3. Fu Shen Mu: treatment of tendon contracture, paralysis, stroke, slanted eyes, palpitations and forgetfulness.
4. Fu Ling and Fu Shen when mixed with Zhu Sha, are called “Zhu Fu Ling” or “Zhu Fu Shen”, to increase the function of calming the heart and calming the nerves. However, Zhu Sha is insoluble in water, so the formula should be changed to powder added to water and drank.
5. Chi Fu Ling: The taste is the same as that of Fu Ling, but the tonic is less strong, so the white Fu Ling is generally used instead of Chi Fu Ling in supplements. The main function of Chi Fu Ling is to clear dampness and heat, so in “Wu Lin Tang” formula it is used with Chi Fu Ling, Zhi Zi, etc. to treat heat and blood (such as acute urethritis, cystitis, and urinary calculi with heat and hematuria). Prescription: Chi Fu Ling 12g, Zhi Zi 9g, Bi Xie 6g, Gan Cao 6g, Dang Gui 9g, Bai Shao 12g, decoction in water.
